To all whom it may concern:

Be it known that I, Josnrn Bosn a MoYiin, a citizen of the. UnitedStates, resi'ding'at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Strip-Coiling Machines, of which the following is a specification.

My invention relates to improvements in strip coiling machines "for usejin rolling mills for coiling sheetsteel in strip form, and the object of my improvement is to produce a machine for coiling such strip material that iscon'structed and arranged so that the coiling 'will be effected in a manner so as to maintain the side e'dges'of the strip on each side in a commonfplane'and the product Will'be straight, and thereby avoid unevenness and irregularity as regards the longitudinal direction of the stock :i. e., whereby the product will be straight instead of crooked.

In the'accompanying drawing v Figure 1 is 'aside elevation of my improved strip coiling machine.

Figure 6 is a. sectionalview of the genera structure on the line 6 6 of Fig. 2.

Figure 7 is a plan viewof thebottom strip guiding and supporting plate and adjacent parts, with certain parts broken away. v

My improved strip coiling machine com prises a frame that is composed substantially of four uprights oifstandards 10 in the'form ofI-beams that are tied together at different elevations by certain cross pieces that support parts of the mechanism and by crossed or spider-like structures that also support parts of the mechanism, the uprights. 10 being at the corners of the frame structure.

Thestrip is coiledbetween two plates'comprising the'bottom plate 11 and the upper plate 12 and is engaged for effecting the coilingby means of a plurality of, fingers 13 that project downwardly through the upper plate12. 7

Themeans of supportfor the bottom plate 11 provided bv the frame comprise a skeletonfspider-lik e base/'14 that is built u of I-beams, held together at thefjunction by means of angle pieces 15 thatfengage with the web portions of said'fI-bea-ms. Secured to the skeleton base letby screws'16 isthe baseproper'li in the form of a circular plate or disc.

A bearing housing structure 18 is secured to the base proper 17 by means of-screws19 that pass through suitable holes in the flange portion 20. Th'ebase proper 17. has a central opening 21 for receiving the reduced bottomIendpor- 'tion 22 of the bottom shaft '23 and resting on theborder portion of said opening .21 is a ball bearing device 2% that serves as" a thrust bearing for supporting. the saidbottom shaft 23. The reduced bottom endlportion 22 mentioned extends through 'theiopens ing' in the ball bearing device24andthe bottom shaft 23 is supportedfrom the said ball bearing device through, the medium of the shoulder 25'at the junction of the body portion 26 of'said shaft 23 and the reduced end portion 22. r I

The bearing housing structure 18rserves as a housing for the ball bearing device .24 and the body portion 26, being in the form of a. sleeve-like structure having a. bore. that fits said body portion26 generally-and that i has an enlarged, chamber? portion '27 at the lower end for housing the ball heating device 24. i

For cooperating with the body portion 26 as a guideand sidebearing 1* provide at the upper end portion of the bearing housing structure '18 abearin'g bushing 28 of brass or other suitable material.

Theupper face of the bearing bushing 28 is opposed to'thebottomlend face of the hub structure "29 of the bottom plate 11, as shown at 30. v v

The bottom plate'll 'issupported on the upper, reducedend p'ortion 31'of the bot: tom shaft'23 by means of a shoulder 32 and is held in non-rotative relation thereto by means ofakey'83. v

The a bottom plate "11, as described, 'is

mounted to rotate freely on a vertical-axis.

The upper face thereof, "asshown at M, is

faced off hoiflzontallyfor engaglng'with.

the bottom edgeo'fthestrip to be coiled. The plate extends laterally beyond. the

fingers l to the extent desired 'correspbnding to the'siz'et ofthe coil-and the lateral edges 35;are',beve1ed to faci litatetheadmis sion of 'the'end of the "strip to the interior coiling space and to avoid damaging the edges of the strip.

The top plate 12 is supported by the lower end portion 36 of the upper shaft 37 a key 38 serving primarily to operatively connect the parts for rotative movementand a screw 39 serving to hold the parts in engagement.

The fingers 13, being twelve in number as shown, extend downwardly through holes 40 in the top plate 12, being slidably engaged with the walls of said holes 40.

The said pins 13 have the body portions extended downwardly substantially across the open space41 between the bottom plate 11 and the top plate 12 and have their upper ends 42 secured in any proper manner in a pin carrier 43 of annular form that loosely overlays the top plate 12 and is mounted for sliding movement along the top shaft 37, and that, furthermore, is adapted to be raised and lowered by means of the lower pin operating lever 44.

An upper shaft operating lever 45, positioned above the lower lever 44, serves as means for raising the top plate 12 and by continued upward movement serves to carry with it the pin carrier 43 and the pins 13, being mounted on and operatively connected with the top shaft 37 in any proper manner for effecting these results.

The structure, involved comprises a spiderlike device that has sliding engagement with the frame and also may serve to provide an auxiliary bearing for the shaft.

IA fixed bearing 46 is provided for the top shaft 37 above the top lever 45 that is supported from the corner posts or standards 10 by means of a fixed spider 47 Adjacentthe upperend of the top shaft 37 is a bevel gear 48 that is held in nonrotative relation thereto by means of a spline 49 which permits the shaft to be raised and lowered relatively thereto for the purpose of changing the open, coil receiving space 41 between the guide plates 11 and 12.

A nut 50 resting on the hub portion 51. of the gear 48 serves as the actual support for the top shaft 37, being engaged with the screw threaded top end portion 52 thereof, a locking screw 53 or any other proper device serving to hold said nut 50 in the position desired for a particular adjustment.

A ,motor 54 serves as the driving means through the medium of a second bevel gear 55 that cooperates with the gear 48. A brake wheel 56 mounted on the motor shaft- 57 may be provided as a convenience for stopping the motor.

Considering the upper lever 45 this extendsthr'ough the frame in the form of a single and generally straight piece, having the handle 58 at the front, under the motor 54; has a counterweight 59 on the rear arm 60; has the fulcrum in the form of the pin bearing 61 that is supported by the crosspiece 62 extending across between the rear posts 10; and has a semi-circular part 63 that extends around one side of the adjacent and opposed shaft engaging devices.

A semi-circular cap structure 64 extends around the other side of said shaft engaging devices and is held to the lever 45 by the screws 65.

The means for operatively connecting the shaft engaging devices and the lever 45 con? prise a pair of laterally projecting pins or. studs 66 on said shaft engaging devices that are entered in suitable slots 67 in the side walls of the enclosing structure composed of the two semi-circular parts 63 and 64, an arrangement that is common in clutch operating mechanism.

The'studs 66 are supported by a ring 68, which, as shown, is composed of two mating parts that are held together by means of screws 69. The ring 68 is housed in a recess 70 in the periphery of the sleeve-like bearing housing 73 to be described, being positioned between shoulders 71 at the ends of said recess. Thus. the lever 45 is connected to the sleeve-like housing 73.

The said sleeve-like bearing housing 73 has a bore that is composed of a central chamber 74 that terminates at the upper and lower ends in the form of reduced parts 75 of smaller diameter, thus providing shoulders 76 at the junctions. shouldered sleeve bearings 77 fill the two end portions of the chamber 74, exterior to the shaft 37, and extend outwardly through the reduced parts 75 and serve as bearings for said shaft 37. 7

In the middle part of the chamber 74 is housed a bearing device 78 that is composed of two similar, mating parts and that cooperates with the opposed portion79 of the shaft 37 as a thrust or lifting device, the said portion 79 being reduced so as to provide shoulders 80 for cooperating with said hearing device 78.

In the case of the lower lever 44, this has the handle 81 at the front end and the part that passes around the interior, shaft enclosing devices is composed of two arms 82 that are extended rearwardly through the frame structure in the form of a fork, a pivotal connection 92 being provided for each of said arms 82, and a counterpoise weight84 being mounted on each of said arms 82. The purpose of such forked, duplex construction is, to straddle the upper lever 45 and the weight 59 carried thereby, and thus avoid obstruction of one by the other.

The arms 82 have slots 85 for cooperating with laterally projecting studs 86 that are carried by a hub 87; Said hub 87 is part of a spider structure 88 that is provided with a set of four arms, the outer ends of which have sliding engagement with guideways 93 thatare provided'imshoe structures 94 that are secured to the corner posts 10 by means of the screws 95. V

As mentioned, the pin car'rier43 has sliding movement along the shaft 37, and this part is driven by the shaft through thei'medium of the pins 13, and to this end the said carrier 43 is provided with an inside and anoutside bearing. Above the pin carrier proper 43 is a sleeve or neck 83 that has a cylindrical portion 84% that serves as the outside bearing and the structure as a whole has a bore 85 that fits the shaft 37 and serves as the inside bearing.

Referring to the bevel gear 48, this is positioned at a fixed elevation above the bearing 46 and as the shaft 37 is raised and lowered relatively thereto the groove 89 for the spline 49 is raised and lowered accordingly and I prefer to positively avoid having the part of the shaft 37 that has the said groove 89 being received within the active part of the said bearing 46 throughout the range of-adjustment that is provided. This result I attain by means of asleeve 90 that is mounted on the shaft 37 and is seated upon the upper end of the structure of the bearing 46, as shown, the said sleeve 90 thus serving as a spacing sleeve.

A bearing bushing 91 may be seated at the upper end of the sleeve 90 for serving as the active bearing for the bevel gear 48, the hub portion 51 of said gear 48 being seated on the upper face thereof.

In use, the pins 13 combine to form a central core for the coil, the inner end of the strip to be coiled being entered radially between adjacent pins and as the pin structure is turned a hold or bite is obtained on the strip, it being understood that some tension is applied to the strip as may be needed. I

The end plates 11 and 12 have fiat and parallel face portions that extend outwardly beyond said central core, formed by the pins 13 mentioned and are spaced to fit against the strip to be coiled and thus serve to confine the strip and maintain parallelism of the side edges thereof. In case the strip is coiled hot and in a condition such that it is liable to be distorted, the effect 'of the arrangement described is to prevent such distort-ion and to correct any deviation from such parallelism of the side edges.

The bevel on the edge of the bottom plate 11 serves to reduce the liability of damage to the bottom edge of the strip as it enters the coiling space.

I claim as my invention 1. A strip coiling machine comprising a frame, a plate operatively supported in said frame for free rotation, 21 second plate opposed to said first plate and separated there from by a coil receiving space, a shaft connected to said second plate, a pin carrier superimposed on. said second plate, coil 'engagingpins supported by'said carrier,""projectin'gthrough holes in 'said se'cond plate and slidable therein, and extending into said space/bearing devices for said shaft, adjusting means engaged with said shaftfor determining the normal separation of" said plates, hand-operated means engaged with said shaft for moving saidsecond plate away from the normal position so as to in crease such separation of the plates and operative to'simultaneously move said can rier and pins and other hand-operated means engaged with said carrier for moving said pins outward and away from said space independent of said first-mentioned handoperated means.
